  • Look Inside

Right heart catheterization is needed for the diagnosis of pulmonary hypertension in patients with primary pulmonary hypertension (PPH), though the procedure was reported to have an unusual high risk. We evaluated the findings of 2-D echocardio-gram in 6 patients with PPH, in comparison with the results of right heart catheterization. Pathological comfirmations were done in 5 cases, except for 1 survivor. The diagnosis of PPH was based on the clinical criteria of research committee of PPH in the Ministry of Health and Walfare in Japan (1976).

On the short axis view in 2-D echocardiogram, left ventricular anterior-posterior diameter/septal-lateral diameter ratio (D2/D1) in end-systole had acceptable correlation with right ventricular systolic pressure (r=0.82). The D2/D1 ratio also showed correlation with pulmonary arterial mean pressure (r=0.86), and LV-RV systolic pressure difference (r=0.90).

With the results above, 2-D echocardiogram is useful for the semiquantitative evaluation of RV overloading in PPH.
